The MNREAD Acuity Charts are continuous text reading acuity charts for normal and low vision.
Often times traditional vision charts only measure general parts of normal vision, such as acuity and contrast. However, many times everyday life scenarios place these two aspects in unique situations. For example, acuity is very important in vision. Testing acuity normally involves a standard eye test. However, when reading the newspaper, the eyes are challenged by small print, continuous text, and several close contact lines. This basic living situation may cause problems for patients with scotomata and may not be detected on conventional acuity charts. Continuous text charts give one more possibility during vision testing.

Near vision test uses the same format as ETDRS 2000 series charts. ETDRS format is calibrated for reliable, repetitive testing using equal difficulty and geometric progression. Vision test uses Sloan
optotype
s for equal difficulty from
optotype
to
optotype
and from line to line creating a uniform level of difficulty. This test features two different ETDRS style permutations for repetitive non memorized testing for both eyes.
